GeForce Go 7900 GTX is a high-end-class level GPU. It can use up to 512MB of dedicated video memory, and it's only available with a DDR3 memory type + a 256 bits Memory Bus Width. Due to its features and unlike the previous GeForce Go models, it should be able to play today's games, that use DirectX 9 (e.g. Sims 3, Anno 1404 and even Crysis) at the lowest settings.
